Adenomyosis of the Uterus

Adenomyosis is a condition in which heterotopic endometrial glands are found in the myometrium. This condition is more commonly associated with multiparity, trauma and surgery to the uterus. Adenomyosis is diagnosed utilizing MRI with an accuracy of 85%. MRI is used because the junctional zone in the uterus is only seen on MRI and it cannot be visualized on CT and ultrasound. The junctional zone is the low signal intensity zone seen on the T2-weighted images on MRI and appears dark, or low-signal, and contains myocytes with lower water content. The junctional zone is the innermost layer of the myometrium.
